Upper GI 2 Flashcards
hiatal hernia - more common in who?
Most common abnormality found on upper GI x-ray
■ More common in older adults and women
2 types of hiatal hernia (hernias slide in pairs)
sliding and Paraesophageal or rolling
sliding hernia (the slide goes down)
slides into stomach when pt is lying down
Paraesophageal or rolling hernia
Fundus and greater curvature of stomach roll up through diaphragm, forming a pocket alongside the esophagus
Acute paraesophageal hernia is a (a cute para needs a paramedic)
medical emergency
hiatal hernia - causes (big)
Structural changes occur with aging
▪ Weakening of muscles in diaphragm ▪ Increased intraabdominal pressure
▪ Obesity
▪ Pregnancy
▪ Heavy lifting
hiatal hernia - symptoms (Hernia - H)
May be asymptomatic
▪ Symptoms include
▪ Heartburn
▪ After meal or when lying supine
▪ Dysphagia
hiatal hernia - complications
■ GERD
■ Esophagitis
■ Hemorrhage from erosion
■ Stenosis
■ Ulcerations of herniated portion
■ Strangulation of the hernia
■ Regurgitation with tracheal aspiration
■ Increased risk of respiratory problems
hiatal hernia - diagnostics (the only 2 you know)
Esophagogram (barium swallow) and endoscopy
hiatal hernia - management - conservative therapy (and what meds?)
ConservativeTherapy
▪ Lifestyle modifications
▪ Eliminate alcohol
▪ Elevate head of bed
▪ Smoking cessation
▪ Avoid lifting/straining
▪ Reduce weight, if appropriate
▪ Use antisecretory agents and antacids
esophageal diverticula (divert the zinc w/ traction and epinephrine)
Occur in 3 main areas
1. Zenker’s diverticulum
▪ Most common location
▪ Above the upper esophageal sphincter 2. Traction diverticulum
▪ Near esophageal midpoint 3. Epiphrenic diverticulum
▪ Above the LES
Esophageal Diverticula Clinical Manifestations (same a gerd)
■ Dysphagia
■ Regurgitation
■ Chronic cough
■ Aspiration
■ Weight loss
Esophageal Diverticula Complications (the MAP diverts up)
■ Malnutrition
■ Aspiration
■ Perforation
Esophageal Diverticula Diagnostic Studies (the same 2)
■ Endoscopy
■ Barium studies
Esophageal Diverticula Interprofessional Care (touch neck)
■ Applying pressure at a point on neck to empty pocket of food
■ Diet may need to be limited to foods that are blenderized
■ Treatment may be necessary if nutrition disrupted
■ Surgery
▪ Endoscopic or open approach (associated w/ morbitidy - usually older ppl)
▪ Most serious complication is esophageal perforation
Esophageal Strictures - over long or short time?
Usually develop over a long time
Esophageal Strictures - causes - most common? (Gerdie is #1 strict)
▪ GERD: most common cause
▪ Ingestion of strong acids or alkalis ▪ External beam radiation
▪ Surgical anastamosis
▪ Trauma
Esophageal Strictures - manifestations (DRW has strictures)
▪ Dysphagia
▪ Regurgitation
▪ Weight loss
Esophageal Strictures - treatment
▪ Dilated endoscopically ▪ Surgical excision
▪ Patient may have a temporary or a permanent gastrostomy (opening in stomach)
Achalasia (atcha is paralyzed)
▪ Rare, chronic disorder
▪ Exact cause is unknown
▪ Peristalsis is absent in lower 2/3 of esophagus
LES pressure ↑
Achalasia - manifestations (atcha can’t swallow w/ a lump in her throat)
▪ Dysphagia
▪ Most common symptom
▪ Liquids and solids
▪ Globus sensation (lump in throat)
▪ Substernal chest pain
▪ During/after a meal
Achalasia Diagnostic Studies
▪ Esophagogram (barium swallow)
▪ Manometric studies of lower esophagus
▪ Endoscopy
Achalasia - treatment - Endoscopic pneumatic dilation (atcha needs balloons)
▪ Outpatient procedure
▪ Dilation of LES using balloons of progressively larger diameters
▪ Repeat dilations are often required
Achalasia - Symptomatic relief (drink water with meals, back atcha)
▪ Semisoft diet ▪ Eating slowly
▪ Drinking with meals
▪ Sleeping with head of bed elevated
Esophageal Varices (varices is varacose) what is the cause?
Dilated, tortuous veins at the lower end of the esophagus caused by portal HTN
Esophageal Varices - Large varices are more likely to
bleed.
Ruptured esophageal varices are the
the most life- threatening complication of cirrhosis and considered a medical emergency.
Peptic Ulcer Disease
Erosion of GI mucosa resulting from digestive action of HCl acid and pepsin
peptic ulcers can occur in (pepi is in the LSD)
▪ Lower esophagus
▪ Stomach
▪ Duodenum
▪ Margin of gastrojejunal anastomosis after surgical procedures
acute peptic ulcer - heal fast or slow?
▪ Superficial erosion
▪ Minimal inflammation
▪ Short duration: resolves quickly when cause is identified and removed
chronic peptic ulcer - how long? and are they common?
▪ Long duration
▪ Muscular wall erosion with formation of fibrous tissue
▪ Present continuously for many months or intermittently throughout person’s lifetime
▪ More common than acute erosions
peptic ulcers - patho
■ Develop only in presence of an acid environment
■ Excess HCl may not be necessary for ulcer development
■ Pepsinogen converts to pepsin in presence of HCl acid and at pH of 2 to 3
■ pH increases to 3.5 or more when
– Food or antacids neutralize the stomach acid
– Drugs block acid secretion
■ Back diffusion of HCl acid into gastric mucosa results in cellular destruction and inflammation
■ Histamine is released from damaged mucosa
■ Causes vasodilation, increased capillary permeability and further secretion of acid and pepsin
Destroyers of mucosal barrier: - Helicobacter pylori (helicopter is ur ease)
Helicobacter pylori (2/3 of world’s pop is infected)
▪ Major risk factor for PUD
▪ Produces enzyme urease
▪ Urease activates immune response
▪ Antibody production
▪ Release of inflammatory cytokines
▪ Leads to increased gastric secretions and causes damage
Destroyers of mucosal barrier: NSAIDs and aspirin
▪ Inhibit prostaglandin synthesis
▪ Increase gastric acid secretion
▪ Reduce integrity of the mucosal barrier
▪ Responsible for majority of non-H. pylori peptic ulcers
▪ NSAIDs in presence of H. pylori increase risk of PUD
Destroyers of mucosal barrier: steroids (steroids shrink)
▪ ↓ Rate of mucosal cell renewal
▪ ↓ Protective effects
Gastric Ulcers (gastric ulcers go everywhere in the stomach) and who gets them? (women stress)
■ Occur in any portion of stomach
■ Less common than duodenal ulcers
■ More prevalent in women
■ Peak incidence >50 years of age
■ More likely than duodenal ulcers to result in obstruction
gastric ulcers - risk factors (3 things) HMR (gassy hummer)
▪ H. pylori
▪ Medications
▪ Bile reflux
Duodenal Ulcers (duo is prevalent and young)
▪ Account for ~80% of all peptic ulcers
▪ Occur at any age and in anyone
▪ ↑ Between ages of 35 and 45 years
▪ H. pylori is found in 90% to 95% of patients
▪ Associated with increased HCl acid secretion
Duodenal Ulcers - Increased risk: (Dua and Zellwiger have ulcers at the door)
▪ COPD
▪ Cirrhosis of liver
▪ Chronic pancreatitis
▪ Hyperparathyroidism
▪ Chronic kidney disease
▪ Zollinger-Ellison syndrome
stress-Related Mucosal Disease (SRMD) (this surgery and trauma is stressing me)
■ Also called physiologic stress ulcer
■ Acute ulcers that develop after major physiologic insult
▪ Trauma or surgery
Gastric ulcers - manifestations- pain how long after meals?
▪ Pain generally high in epigastrium
▪ 1–2 hours after meals
▪ “Burning” or “gaseous”
▪ Food aggravates pain if ulcer has eroded through gastric mucosa
Duodenal ulcer - manifestations - pain how long after meals? (Dua is 25)
▪ Pain in midepigastric region beneath xiphoid process
▪ Back pain—if ulcer is located in posterior aspect
▪ 2–5 hours after meals
▪ “Burning” or “cramplike”
▪ Tendency to occur, then disappear, then occur again
Gastric ulcer - G
great pain
Duadenal ulcer - D
decrease pain
3 complications with ulcers (think if they rip off or block)
▪ Hemorrhage
▪ Perforation
▪ Gastric outlet obstruction
▪ All considered emergency situations
hemmorhage - does pain increase or decrease?
▪ Most common complication of PUD
▪ Dudoenal ulcers cause more UGIB (upper GI bleeds) episodes than gastric ulcers
▪ Clinical Manifestations:
▪ Changes in vital signs, ↑ in amount and redness of aspirate ▪ Signals massive upper GI bleeding
▪ ↑ Amount of blood in gastric contents
▪ ↓ Pain because blood neutralizes acidic gastric contents
Perforation
■ Occurs when ulcer penetrates serosal surface with spillage of contents into peritoneal cavity
